  What is a DVR?
  Comparison Chart (DVR vs. CCTV)

DVR (Digital Video Recorder) is a newer recording system that changes the signals of analog image in CCTV cameras into the digital data. DVR compresses and retrieves the recorded video in H.263 or MPEG format for a clearer playback. DVR security systems have more features compared to older CCTV systems such as:

  • Has high-speed multi-recording capability that allows multiple channels to be viewed on one screen.
  • Can record high quality video even after continuous and repeated use.
  • Can compress the recorded video down to a smaller size to be able to record long-term without interruptions.
  • Use hard drives to store video which eliminates the need for tapes or CDs.
  • Automatically saves to the hard drive and can overwrite older videos when the hard drive becomes full.(If the video needs to be saved and not overwritten, the hard drive must be replaced).
  • Can surveillance the area clearly by software and can record from additional cameras without the need for more recording equipment.
  • Make it easy to check a specific period of time by date, time, and camera number.
  • Can instantly playback a specific period of time without the need to rewind or fast forward.
  • Can view, search, and playback recorded video remotely through LAN and via internet.
  • Can playback video while the system continues to record.
  • Can remotely control cameras that use PTZ drivers without the need for additional equipment.
  • Can detect motion and capture video without needing a motion sensor. The software for DVRs allows the system to digitally detect motion.

DVR surveillance systems can maximize security and minimize loss for your business.

  DVR Internal Architecture
  • Capture Board: A device which captures analog image signals and changes it into digital images.
  • Main Processor: The main processing component of DVR which processes image compression and processing.
  • Storage Device: Stored media such as a hard disk drive or CD.
  • Display Device: Display media such as a CRT or LCD/LED Monitor.

  Kinds of DVR

A PC-Type DVR is a PC running on Windows 98 or NT with a DVR capture board installed. It is easily customizable with PTZ cameras, sensor controls, and related software due to the flexible nature of a PC.

Stand-alone Type DVR

A stand-alone system uses a specialized board designed for DVR use. Problems that could occur on a PC have been prevented at the initial stage of product planning. Unnecessary components that exist on a PC are excluded which provides a very stable surveillance system. Although fewer parts are included, a stand-alone system tends to cost more due to it being specifically designed for DVR use.

CCD Camera

A charge-coupled device camera can be used with DVR devices and can be used in any general CCTV system that supports NTSC or PAL. CCD cameras transmit images through digital signals rather than analog to produce high quality images.

Pan/Tilt Driver

A pan/tilt driver is a device which can rotate a camera's focus left and right, up and down, and zoom in and out by operation of motor through an electric signal. It allows a user to change the surveillance area of a camera remotely at will. Choose from a variety of pan/tilt drivers for indoor or outdoor use.
